Abstract (en)
In a magnet switch (50) for a starter, a first contact portion (70) and a second contact portion (80) are connected in parallel between a battery and a motor. The first contact portion (70) makes contact through a resistive component so that the motor starts rotation at low speed. By this, a pinion (25) is pushed in an axial direction by an axial component of splines (20a, 25a) and brought into mesh with a ring gear in a condition that its rotation is restricted. Thereafter, the second contact portion (80) makes contact in accordance with further movement of a plunger (52) so that electric power is fully supplied to the motor through the second contact portion (80), thereby starting engine. A fixed contact (71) of the first contact portion (70) is made of a carbon material. The resistive component is provided by the carbon material. <IMAGE>
